The iConverter RS232 is a managed serial RS-232 to fiber converter that transmits serial protocol over fiber media. The RS232 media converters operate in pairs, extending serial distances over fiber up to 120km, which improves noise immunity from electrical and magnetic interference. The RS232 is available with a single-mode dual fiber, multimode dual fiber or single-mode single-fiber transceiver. The serial port interface is available with either a DB-9 female connector or terminal block connector for field wiring. The RS232 automatically detects the signal data rate of the connected serial device, ranging from 110 bps to 921,600 bps. It also automatically adjusts to changes in the connected device's data rate during operation without reconfiguration or interruption of service. Connection to DTE or DCE devices are configured by an easily accessible DIP-switch on the front-panel of the module. This feature eliminates the need to use a null-modem cable when connecting two serial devices of the same type. A built-in Fiber Loopback DIP-switch provides easy validation of the entire fiber segment without interrupting fiber operations. iConverter RS232 modules are hot-swappable and can be mounted in a 19-Module (2U high) or 5-Module (1U high) rack mountable chassis (19-inch or 23-inch) with redundant AC, 24VDC or 48VDC power supplies. They can also be mounted in a 2-Module AC or 18 to 60VDC powered chassis, or in a 1-Module AC or DC powered chassis.
